fluoroalkyl group; b represents an integer of 1 to 3; m represents an integer of 0 to 2; n represents an integer of 1 to 3; and b, m and n satisfy b+m+n=4,
where X each represents a hydrogen atom or acid labile group; and a represents an integer of 1 to 5. It is possible by the use of this positive photosensitive resin composition to provide a film with high resistance and heat-resistant transparency and provide an electronic component with such a film.
